Whether these non\u2010invasive parameters can also predict ventricular tachycardia (VT) recurrence after radiofrequency catheter ablation (RFCA) is unknown. Of interest, patients with a wide QRS\u2010complex have been excluded from clinical studies on J\u2010waves, although a J\u2010wave like pattern has been described for wide QRS.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>We retrospectively included 168 patients (67 \u00b1 10 years; 146 men) who underwent RFCA of post\u2010infarct VT.

Kaplan\u2013Meier curves revealed that both J\u2010wave pattern and fQRS were associated with VT recurrence.
